Turner Construction is still the biggest contractor in the country, and it isn’t close. For the sixth year running, Turner tops ENR’s 2026 Top 400 Contractors list, with 2025 revenue climbing to $28.3 billion from $20.2 billion the year before. That kind of jump says as much about where the work is as about any single firm.
What’s pulling the top of the ranking
The growth is lopsided. Data centers, semiconductor fabs, and big healthcare campuses are steering enormous volume toward the handful of builders large enough to staff them, while smaller commercial and institutional work stays flat. Turner’s own book runs from hospitals to waterfront redevelopment, including Boston’s Commonwealth Pier revitalization. The firms right behind it on the list are chasing the same megaprojects.
A two-speed contractor market
Read the Top 400 next to the broader numbers and the split is obvious. The megaproject boom has been kind to the largest contractors and mostly irrelevant to mid-size regional firms that don’t bid gigawatt data campuses. Revenue records at the top don’t mean the whole industry is booming; they mean the biggest jobs are getting bigger and consolidating with fewer players.
Whether that concentration holds depends on the AI and chip buildout staying on its current trajectory. For now, being big enough to take on a $2 billion job is the single best predictor of who’s growing.
